Arakawa Lab (Semiconductor Photonics Engineering Lab)
Machine-translated · View original
A lab studying semiconductor devices that control light, along with plating technology.
AboutAbout the lab
Controlling light with semiconductors, building circuits by plating.
The Arakawa Lab studies semiconductor-based devices such as optical modulators, optical switches, and semiconductor lasers, as well as photonic integrated circuits.
The lab also works on optical biosensors and gas sensors, and related technologies.
Its other main area is advanced plating technology for making electronic and optical devices, and its applications.
The lab collaborates with other labs at Yokohama National University and with a group at the Materials and Surface Engineering Research Institute of Kanto Gakuin University.
Key terms
- Quantum nanostructure
- A fine artificial material. Using it in optical devices is expected to deliver performance superior to anything before.
- Microring resonator
- A ring-shaped optical resonator. This lab uses it in wavelength-selective filters, sensor elements, and more.
- Electroless plating
- Plating that forms a metal film on a substrate through a chemical reaction in a solution, without passing electric current. It is used to form metal patterns.
